A number of GWAS risk alleles are in reasonable LD (r2>0.3) with coding SNPs on the array and several of the latter show nominal associations (p<0.05) with breast cancer risk including SNPs in STXBP4, ZNF45, and ZNF404 which are all worth evaluating as candidate loci potentially explaining the index GWAS associations. The gene discussed is STXBP4; the disease is breast carcinoma.
